The phrase refers to the availability of a live or real-time audiovisual feed specifically designed for Apple’s mobile operating system. It indicates that content can be viewed immediately on iPhones, iPads, and iPod Touch devices, without significant delay. For example, a sports broadcast being “onstream for iOS” means users with these devices can watch the game as it happens.
Delivery of real-time content to the iOS ecosystem is significant due to the widespread adoption of Apple devices. It allows for immediate access to news, entertainment, and events regardless of the user’s location. Historically, ensuring seamless delivery on iOS required careful consideration of Apple’s protocols and codecs, necessitating specific encoding and delivery methods to optimize performance and user experience.
